当某个程序打开时，如何在Cinnamon中禁用Alt-Tab应用程序切换？

我使用emacs并在某些模式下将填充命令设置为Alt-Tab，并且作为习惯的生物，希望保持这种方式。

有没有一种简单的方法可以在emacs打开时通过Alt-Tab禁用应用程序切换？

我有一个解决方案。 所有你需要的是，启动这个观察者脚本：

#!/bin/bash keySwitchApplication="switch-applications" keySwitchApplicationBackward="switch-applications-backward" backupSwitchApplications="$(gsettings get org.gnome.desktop.wm.keybindings "$keySwitchApplication")" disableSwitchApplications="$(gsettings get org.gnome.desktop.wm.keybindings "$keySwitchApplication" | sed "s/\,*\s*'Tab'//")" backupSwitchApplicationsBackward="$(gsettings get org.gnome.desktop.wm.keybindings "$keySwitchApplicationBackward")" disableSwitchApplicationsBackward="$(gsettings get org.gnome.desktop.wm.keybindings "$keySwitchApplicationBackward" | sed "s/\,*\s*'Tab'//")" disabled="0" while true; do isActive=$(wmctrl -lx | awk -v search=$(printf 0x0%x $(xdotool getactivewindow)) -v wm_class="$wm_class" '{ if($1 ~ search && $3 ~ /emacs/) print $3 }') if [[ "$isActive" != "" ]]; then # echo "active" if [[ "$disabled" == "0" ]]; then # echo "disable shortcut" gsettings set org.gnome.desktop.wm.keybindings "$keySwitchApplication" "$disableSwitchApplications" gsettings set org.gnome.desktop.wm.keybindings "$keySwitchApplicationBackward" "$disableSwitchApplicationsBackward" disabled="1"; fi else # echo "not active" if [[ "$disabled" == "1" ]]; then # echo "enable shortcut" gsettings set org.gnome.desktop.wm.keybindings "$keySwitchApplication" "$backupSwitchApplications" gsettings set org.gnome.desktop.wm.keybindings "$keySwitchApplicationBackward" "$backupSwitchApplicationsBackward" disabled="0" fi; fi; sleep 1 done

该脚本在无限循环中检查窗口类emacs并禁用/启用Alt + Tab和Shift + Alt + Tab

如果出现任何问题，您可以将条目重置为默认设置：

 gsettings reset org.gnome.desktop.wm.keybindings switch-applications gsettings reset org.gnome.desktop.wm.keybindings switch-applications-backward 

就我而言：

 % gsettings reset org.gnome.desktop.wm.keybindings switch-applications % gsettings get org.gnome.desktop.wm.keybindings switch-applications ['Tab', 'Tab'] % gsettings reset org.gnome.desktop.wm.keybindings switch-applications-backward % gsettings get org.gnome.desktop.wm.keybindings switch-applications-backward ['Tab', 'Tab']

一种丑陋的hackish方式浮现在脑海中……

键盘设置应存储在： ~/.config/dconf/user如果您有两个文件，一个是Alt+Tab在系统范围内启用，另一个是Alt+Tab全局禁用，理论上可以交换它们。

简单的脚本将：

1. 备份Alt+Tab Enabled
2. 将Disabled Alt+Tab复制到Disabled Alt+Tab Enabled Alt+Tab
3. 运行Emacs
4. Emacs关闭后，将文件复制回原样

该脚本将用于打开/运行Emacs

我不知道它是否会起作用，为了安全起见我会首先在VB中尝试它，现在我没有时间尝试不幸…
